Fedora 43 installation on entire disk

I had installed F42 using dual-boot with windows and I could boot with grub selecting Fedora (last 3 kernels), windows, UEFI and recovery.

Now I have installed Fedora 43 using the entire disk, and now grub doesn’t show up, the PC boots immediately into Fedora.

I tried to modify /etc/default/grub like this

GRUB_TIMEOUT_STYLE=menu
GRUB_TIMEOUT=5
GRUB_DISTRIBUTOR=“$(sed ‘s, release .*$,g’ /etc/system-release)”
GRUB_DEFAULT=saved
GRUB_DISABLE_SUBMENU=true
GRUB_TERMINAL_OUTPUT=“gfxterm”
GRUB_CMDLINE_LINUX=“rhgb quiet rd.driver.blacklist=nouveau,nova_core modprobe.blacklist=nouveau,nova_core”
GRUB_DISABLE_RECOVERY=“true”
GRUB_ENABLE_BLSCFG=true
GRUB_GFXMODE=1920x1080

and regenerate the config with

sudo grub2-mkconfig -o /boot/grub2/grub.cfg

without any luck.

Here the partitions

lsblk -f
NAME FSTYPE FSVER LABEL UUID FSAVAIL FSUSE% MOUNTPOINTS

Does this help?

Press esc a few times or left shift on startup to view grub menu.

Auto hide should automatically be disabled on multi-boot machines.
On my machines (still f42) this works: laptop with only Fedora: boots directly to Fedora. desktop machine with dual-boot: shows Grub, no manual config was required on either machine.

If this doesn’t work in F43, this is a bug/regression that should reported.

Right, I think OP previously had a dual-boot setup (without auto-hide) and has now wiped the disk and replaced with a single-boot setup, which does default to auto-hide.
